是系统定义的默认变量,会返回当前执行的脚本文件 通过os.path.abspath(file),得到文件的绝对路径字符串 调用os.path.dirname(file),得到文件所在目录的路径 这样重复调用os.path.dirname(os.path.dirname(os.path.abspath(file))),可以得到当前文件的上上级目录,这个功能和强大 3、Python对象的创建和赋值 Python完全...
accessed = dt.fromtimestamp(os.path.getatime(source)) accessed = Time(tz.localize(accessed))print("Source\n===")print("Created: {}\nModified: {}\nAccessed: {}".format( created, modified, accessed)) 准备工作完成后,我们可以使用CreateFile()方法打开文件,并传递表示复制文件的字符串路径,然后是...

>>> a, b = 257.0, 257.0 >>> a is b True Why didn't this work for Python 3.7? The abstract reason is because such compiler optimizations are implementation specific (i.e. may change with version, OS, etc). I'm still figuring out what exact implementation change cause the issue, ...
